Food plays an important role in influencing the students' learning behavior and achievement through a few basics. This study aimed to improve nutritional status (especially hemoglobin and lipid profile) and developing the mental efficiency (especially perception , remembering and attention )  in adolescence using various rich sources of omegas (3 , 6 and 9). Also, to compare the effectiveness of natural food sources with the medical supplements of them. Forty eight adolescents (12-15 yrs) with institutionalized nutrition were subjected and divided to 3 groups (each of 16;  8 M & 8 F ). The first group was served as control , while the second and the third ones were enriched and supplemented equally with natural and medical sources of omegas for three consequence months. Nutritional assessment was also surveyed for the subjects (24 hrs. recall for three continuous days). Biological analysis for  Hb. , AST, ALT , TG , TC , HDL-C , LDL-C  and VLDL-C  had been taken place pre and post supplying intervention. Psychological test was applied also pre and post supplying intervention to assess the perception, attention and remember for them.
Results showed that both kinds of intervention increased significantly ( p≤ 0.01 ) Hb and HDL-C , while decreased significantly ( p ≤ 0.01 )  ALT , AST , TG , TC , LDL-C . VLDL-C in serum of  the studied adolescents. On the other hand , psychological test revealed significant development statistically (p ≤ 0.01 ) after three months of interventions comparing with the control group or even with the pre test assessment.
In conclusion : supplementation with natural or medical omegas for adolescence could improve the mental efficiency ( especially perception, attention , remember ) after three months without discrimination for the source used.
